How Crowded Is Rosie the Riveter WWII Home Front National Historical Park in August?

August runs about 1.2× Rosie the Riveter WWII Home Front National Historical Park's average month, which makes it a busy month here — roughly 10% of the park's yearly visitors come in August.

In a typical August the park sees roughly 4,900 recreation visits, based on National Park Service monthly counts from 2013 to 2025.

That makes August the 1st-busiest of the park's twelve months, sitting between the July peak (1.2×) and the January low (0.7×).

On our Best Time to Visit score August rates 51/100 ("Fair"), versus the top-rated October at 70/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical August weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 72°F and an overnight low around 56°F, with about 0.1" of precipitation.

That average of about 64°F is a comfortable range for hiking and being outdoors all day.

August falls inside the park's busiest stretch: June, July and August together pull about 29% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 13.5 hours of daylight in August to explore — between the 9.4-hour midwinter low and the 14.6-hour summer high.

Park-wide, 2024 drew 34,913 recreation visits, down 12.5% from 39,883 in 2023.

Across the past decade overall visitation has eased about 14.8%, so August may feel a touch quieter than it once did.
